Description
Technical field
The invention belongs to the technical field of automobile-used rubber production, being specifically related to a kind of sidewall rubber of the resistance to ozone ageing for gently blocking.
Background technology
Tire is assemblied on wheel rim or wheel shaft, is the linker between vehicle and road, runs and the circular ring type elastomerics of landing for vehicle or aircraft.A set of tire by the inner tube of a tyre forms by 3 usually: cover tire, the inner tube of a tyre, rim strip.Wherein cover tire is the type shells body for bearing motive power; The inner tube of a tyre for keeping the interior pressure of tire, with the annular elastomerics of tyre valve; Rim strip the face of conjunction not by the endless belt of wheel rim wearing and tearing for the protection of the inner tube of a tyre.And tyre surface and tread, be tyre protector position, the cover tire glue-line namely on belt or buffer layer, has certain section form, has decorative pattern.The casingply of wheel crown part, buffer layer not only can be protected from damage; Can make there is good gripping power between tire and ground simultaneously, avoid the longitudinal and lateral movement of tire to affect the rideability of automobile.
Tire is one of major parts of automobile, for automobile, like the both feet being people, is the travel mechanism of automobile.Tire is arranged on the effect of automobile: 1, bear automobile and its institute's weight-carrying capacity, this is called supporting capacity; 2, transmit the reactive force that automobile is sailed, draws, accelerates, turns to and braked earthward, as functions such as motivating force, tractive force, damping force and steering forces, this is called the requirement of adaptation automobile dynamic quality, makes the ability of automobilism; 3, can make that automobile is driven freely under various weather, road surface and velocity conditions, the function of operation stabilization and high-speed secure, this is called security; 4, damping vibration, reduce noise, take advantage of the function that seat is comfortable, this is called comfortableness.
Wherein the body cord orientation of radial is as the terrestrial meridian, centered by wheel shaft, from a tyre bead to another tyre bead, and radial array.Although belt cord is diagonal cross arrangement, with crown medullary ray in very little angle.It is 90 ° that body cord presses crown medullary ray in meridian direction arrangement; And have cord to arrange almost close to the belt bundle banding carcass of circumferential direction.
Along with the raising of automobile driving speed and the improvement of highway pavement, the especially development of motorway, tire quality performance is had higher requirement, mainly contain following basic demand: 1. higher portative power and good shock-absorbing capacity; 2. stronger tractive force and good braking ability; 3. good cornering ability and directional stability ability; 4. good abrasion resistance and endurance quality; 5. high security and low-rolling-resistance.
The key factor affecting Using Life of Tyre is ozone ageing, and ozone ageing makes tire easily chap, and cause tire major injury, and the sidewall rubber in tire is the easiest ozone ageing, so need a kind of sidewall rubber of resistance to ozone ageing.
